A motorcycle can travel 70 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 60 km?

Given: [tex]\(1 \text{ mile} = 1.6 \text{ km}\)[/tex]

Select one:
a. 0.2
b. 0.5
c. 0.8
d. 1.4



Answer :

To determine how many gallons of fuel a motorcycle will need to travel 60 kilometers, we need to follow a few logical steps:

1. Convert kilometers to miles:

Since we know that [tex]\(1 \text{ mile} = 1.6 \text{ km}\)[/tex], we start by converting the given distance in kilometers to miles.

The distance to be traveled is 60 kilometers. Using the conversion factor:

[tex]\[ \text{Distance in miles} = \frac{\text{Distance in kilometers}}{\text{Conversion factor}} \][/tex]

[tex]\[ \text{Distance in miles} = \frac{60 \text{ km}}{1.6} \][/tex]

2. Performing the division:

[tex]\[ \text{Distance in miles} = 37.5 \text{ miles} \][/tex]

3. Calculate the gallons of fuel needed:

The motorcycle can travel 70 miles for each gallon of fuel. To find out how many gallons it will need to travel 37.5 miles, we can use the formula:

[tex]\[ \text{Gallons needed} = \frac{\text{Distance in miles}}{\text{Miles per gallon}} \][/tex]

[tex]\[ \text{Gallons needed} = \frac{37.5 \text{ miles}}{70 \text{ miles/gallon}} \][/tex]

4. Performing the division:

[tex]\[ \text{Gallons needed} \approx 0.5357 \text{ gallons} \][/tex]

Given the options:
a. 0.2
b. 0.5
c. 0.8
d. 1.4

The answer closest to 0.5357 gallons is option b.

Therefore, the motorcycle will need approximately [tex]\(0.5\)[/tex] gallons of fuel to travel [tex]\(60\)[/tex] kilometers.
